Well, more than that, since I don't really want my DSL pipe saturated with TV that I'm not watching, you need some way for the CPE to tell the ISP "send me stream N" I suppose with some sort of spanning three thing it'd even be posssible to do that at multuple levels, so the streams are only fed to people who have clients for it.
